I would say they should contain the name and full path of the entry -- the symlink, NOT the linked file. They kind of have to, right, otherwise they'd have to be method calls that potentially call the system.

Sorry, I don't remember who but someone proposed to add the follow_symlinks parameter in scandir() directly. If the parameter is added to methods, there is no such issue.

I like the compromise of adding an optional follow_symlinks to is_xxx() and stat() method. No need for .lstat().

Again: remove any garantee about the cache in the definitions of methods, instead copy the doc from os.path and os. Add a global remark saying that most methods don't need any syscall in general, except for symlinks (with follow_symlinks=True).
